Answer:
150cw + 80w^2
Step-by-step explanation:
so we start with
(15c + 8w)  • 10w
we would distribute it to the 15c and the 8w
once we distribute it it would become 
150cw because of 15c  • 10w 
and 80w^2 because of 8w • 10w
 
        
             
        
        
        
Answer:
x = -6 and x = 4
Step-by-step explanation:
In math, the critical points of a function are the points where the derivative equals zero.
So, first we will find the derivative of the function. The derivative is:

Now, we are going to make the derivative equal zero and find the answers of the equation. 

So we have that the critical points are the answers to this equation:

and 

Thus, the critical points are x=-6 and x=4
 
        
             
        
        
        
answer:
d: 30 
all angles in a triangle have a sum of 180 degrees. Just add 50 and 100 (so 150) and do 180-150=30.
